VM freezes after host resume from sleep mode

[tomaskcz]

Host : Ubuntu 18.04.1 Mate
Quest : Ubuntu 18.04.1 Mate
(both the same, fully updated, default kernel)

After host PC laptop is resumed from sleep mode, the quest linux VM is unresponsive. The last messages to be seen in VM log

Code: Select all

08:55:41.925867 Console: Machine state changed to 'Running'
08:55:41.925867 VMMDev: vmmDevHeartbeatFlatlinedTimer: Guest seems to be unresponsive. Last heartbeat received 4 seconds ago

It doesn't happen always, but very often. The VM has to be powered off by Virtualbox menu or close button. Untill so, it loads 100% one CPU.

This is probably similar case to other issues reported with resuming from sleep, I didn't find any solution.

I've been using Virtualbox since Innotek and this is the first time I encountered such problems.

Same symptoms reproduced on virtualbox 5.2.10 and 5.2.18

Yes, it appears so. That's why I decided to create a meta-thread to collect all the reports so that the developers might have a better chance of seeing all the data in one place.

Please put a note to any thread if there is a solution available.

Untill then I switch to KVM.

Thank you.
